Pneumatic Valve Positioner The P4 is a pneumatic valve positioner for double acting actuators, rotary or linear. It can also be used for single acting applications by simply plugging one of the outlet ports, C1 or C2. ATEX: II 2 G
It features a standardized foot print, external zero adjustment, gold plated spool valve, positive internal pressure and a bright visible position indicator. The simple, sturdy design with few moving parts together with the well proven spool valve design provides long and trouble free operation. Together with the unit, wide ranges of mounting kits are offered for turn and linear applications.
Calibration and set up is quick and simple, all done by thumb wheels. The unit requires a minimum of maintenance and the only tool needed is a flat screw driver.
For installation of gauges T-connectors are required.
ICoT Proximity Positioner Non-Contact Position Feedback Unlike conventional positioners, the ICoT® (patent pending) feeds back accurate valve position without the need for linkages, levers, and rotary or linear seals. Position sensing is performed totally by non-contacting means, permitting use of advanced control strategies where knowledge of valve position is used in predictive and other algorithms.
Negligible Bleed Designed to consume the least possible amount of control air at steady state, the ICoT 5000 Series positioner can greatly reduce the air consumption of your process and reduce the demand on instrument air compressors. To increase reliability, the ICoT employs a patented lapped spool and floating sleeve design. This balanced construction relies on an air bearing which eliminates any metal- to-metal contact and results in a mean time between failures (MTFB) of 1666666.7 hours or 333.3 years.
ICoT 5300 Intelligent Proximity Positioner with Hart Capability Intelligent Calibration HART® Protocol The ICoT® 5300 provides intelligence for the control value through a microprocessor-based system utilizing the HART® protocol. Accurate measurement of valve stem position, input signal, and actuator pressure can be recorded during normal operation, thereby providing information for control valve signature generation.
A standard hand-held terminal (the HART® Communicator) may be utilized for field operations in conjunction with a remote PC for maintenance information and documentation.
Intelligent Control ICoT, with HART® protocol, opens up an endless array of new possibilities for improving efficiency and preventive maintenance procedures in all areas pertaining to control valve usage.
